Selections, cut buffers, and drag-and-drop are the mechanisms used in the X Window System to allow a user to transfer data from one window to another. Selections and cut buffer are typically used when a user selects text or some other data in a window and pastes in another one. Drag-and-drop is used when a user selects something in a window ...
When mounting branches, the priority of one branch over the other is specified. So when both branches contain a file with the same name, one gets priority over the other. The different branches may be either read-only or read/write file systems, so that writes to the virtual, merged copy are directed to a specific real file system.
Transferring data to and from the 8X300 is a two-step process: Step 1: Using one of the MOVE, ADD, AND, XOR or XMT instructions and specifying one of the virtual registers IVL (left bank) or IVR (right bank) as the destination, an address is output on the IV bus, along with Select Command and Bank Select signals. This may have to be repeated if ...
The cut command removes the selected data from its original position, and the copy command creates a duplicate; in both cases the selected data is kept in temporary storage called the clipboard. Clipboard data is later inserted wherever a paste command is issued. The data remains available to any application supporting the feature, thus ...
Multiway branch is the change to a program's control flow based upon a value matching a selected criteria. It is a form of conditional statement.A multiway branch is often the most efficient method of passing control to one of a set of program labels, especially if an index has been created beforehand from the raw data.
In computer engineering, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous "pipeline") performed by different processor units with different parts of instructions ...

Given such data, a branch table can be extremely efficient. It usually consists of the following 3 steps: optionally validating the input data to ensure it is acceptable (this may occur without cost as part of the next step, if the input is a single byte and a 256 byte translate table is used to directly obtain the offset below). Also, if there ...
